SPECIFICATION formingpart of Letters Patent No. 6Q8 ,595, date clAugust 9, 1898.

- Application filed m 12,1896. Serial no. 591,308. (No model.)

To ctZZ whom it mcty concern:

Be it known that I, JOHN H. GooDFELLow,

of Lowell, in the county ofMiddlesex and State of Massachusetts, have invented a new 5 and useful Improvement in Store-Service Apparatus, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in store-service apparatusof that description in which the carrier is mounted on a way and is adapted to engage with a propelling-wire and is put in motion by the separation of the propelling-wire from the way. It more particularly relates to improvements in the mechanism for operating the propelling-wire and for receiving the carrier at the end of a trip. r

The invention consists in the novel construction, combination, and arrangement of parts, such as will be hereinafter fully de scribed, pointed out in the appended claims, and illustrated in the accompanying drawings. v

In the accompanying drawings, Figure l is a side elevation of a store-service apparatus embodying the invention. Fig. 2 is a plan view of the same. Fig. 3 is a sectional view on the line 3 3 of Fig. 2.

Similar letters of reference designate corresponding parts in the several views.

A standard A issecured to a support of any construction suitable in the premises. It carries at its lower end the step a. Attached-to the forward end of the step is one end of the way B. The other end of the way is secured in any suitable manner. Projecting from the upper face of the step a is a recessed log a, provided with a set-screw a A bracket C is adj ustably mounted 011 the standard A. It has a collar encircling the standard and a set screw c passing through a side of said collar and impinging on the periphery of the standard. By means of the set-screw the bracket can be secured in its adjustments on the standard. A hood 0 projects'from the under side of the bracket and has journaled therein the sheave 0 From the hood a rope-guide 0 extends. In

the collar 0", carried by the outer endof the bracket C, is mounted the upper end of the guide-rod D. ;The lower end (I of the latter is bent at substantially right angles to the upper part of the "rod and is seated in the recess in the lug a, wherein it is adj ustably secured by the set-screw a On the guide-rod D a sliding block E is mounted. From the rear of the block a re- 'cessed lug 6 projects. In the recess in the said lug is secured an end of the operating cord or rope e The latter passes upward through the guide 0 over the sheave c and downward through an opening in the step a and has attached to its free end the handle 6 By means of this cord the sliding block may be moved'on the guide-rod.

Hinged on each side of the step a is a jaw F.

A knuckle-joint f connects one end of the jaw to the heel of the step. These jaws are normally held apart at their free ends by the spring f, interposed between them. Their movement apart is limited by the stops f projecting from the crossbar f secured to the under side of the step by the screw f They are prevented from moving vertically by the said cross-bar and the lugs f project- ;ing from the sides of the step. The movement of the jaws toward each other is limited by the step a, with which they contact when brought together. The outer or free ends of the jaws are elongated and somewhat elastic, and at their outer ends, as at f, they diverge, as shown in Fig. 2. The inner diverging faces of the jaws have secured thereto strips of leather f 5 The propelling-wire H is normally substantially parallel with the way 13 and is secured at one end to the eye a, carried by the sliding block E. The other end of the wireis secured in any suitable manner. The end of the wire engaging with the eye 6 is twisted to form a screw and has secured thereon the rubber buffer h. The screw formation of the wire serves to hold the buffer in place. As the guide-rod on which the sliding blockmoves 5 can be adjusted to or from the direction'from which the wire approaches, the tension of the said wire can be regulatec. From the opposite sides of the sliding block E the curved arms 6 project. They extend I00 outwardly and downwardly, as shown in Fig.

3, and form a yoke. Their lower ends di-= in 31111 er.

spring f.

A carriage K is mounted on the way B and I It coni engages with the propelling-wire I-I. sists of the narrow elongated frame and has journaled in each end of said frame the upper and lower rollers 70 and 70 respectively. To the under side of the carriage is removably attached the receptacle in any suitable The dimensions of the frame 70' are such that it will enter between the jaws F and be grasped by the latter, the said jawsspringing apart slightly to admit the car-5 riage. r

leather-covered inner faces of the same.

by the impact and the friction between the leather-covered faces of the jaws and the sides 3 of the frame. If these obstacles should not be sufficient to entirely stop the carrier, further movement of the same would cause the frame to strike against the rubber buffer h on The carrier could not rebound after entering between the jaws, as the latter grasp the frame and hold the carrier.

To propel the carrier, the operator, through the cord 6 raises the sliding block E and thereby separates the propelling-wire from the way back of the upper and lower rollers mounted in the end of the frame 7;. ward movement of the sliding block releases the jaws F from the yoke formed of the arms 6 and allows them to be forced apart by the spring f and thereby frees the carriage from the jaws. The separating of the propellingwire from the way back of the rollers of the carriage puts the latter in motion with a momentum sufficient to carry it to the other end of the way. I/Vhen the cord is released, the movable parts resume their normal positions either by the action of gravity or their springs.

Having thus described the invention, what The up I claim, and desire to secure by Letters Patent, is

1. In a store-service apparatus, the combination of a way, a propelling-wire, means for separating said wire and said way, a carriage adapted to engage with said way and said wire, hinged jaws for engaging with said carriage, and a movable yoke for engaging with said jaws to hold the same closed.

2. In a store-service apparatus, the combination of a way, a propelling-wire, means for separating said way and said wire, a carriage adapted to engage with said way and said wire, hinged jaws for engaging with said carriage, a spring pressing said jaws apart, and a movable yoke for engaging with said jaws to hold the same together against the action 1 of said spring.

3. I In a store-service apparatus, the combination of a way, a propelling-wire, means for separating said way and said wire, a carriage adapted to engage with said way and said wire, hinged jaws for engaging with said carriage, a sliding block, and a yoke carried by said block for engaging with said jaws to hold the same closed.

4c. In a store-service apparatus, the combination of a way, a propelling-wire, means for separating said way and said wire, a carriage adapted to engage with said way and said wire, hinged jaws for engaging with said carriage, an adjustable guide-rod, a block movably mounted on said rod, and a yoke carried by said block for engaging with said jaws to hold the same closed. 5. In a store-service apparatus, the combination of a standard, a step carried by the said standard, a way attached at one end to said step, a bracket mounted on said standard, a guide-rod carried by said step and said bracket, a sliding block mounted on said rod, means for moving said block, a propellingwire connected at an end with said block, a carriage adapted to engage with said way and said wire, jaws hinged to said step for engaging with said carriage, and a yoke carried by said block for engaging with said jaws to hold the same closed.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 4th day of May, A. D. 1896.
